I attached the working and the answer to the question below. I hope I was able to help.
Please note that C = speed of light (2.998 × 10⁸ m/s), ν = frequency and λ= wavelength.
Answer:
1.30 g
Explanation:
La reacción que toma lugar es:
- 2Mg + O₂ → 2MgO
Primero <u>convertimos 3.28 g de MgO en moles</u>, usando su <em>masa molar</em>:
- 3.28 g ÷ 40.3 g/mol = 0.081 mol MgO
Después <u>convertimos 0.081 moles de MgO en moles de O₂</u>, usando los <em>coeficientes estequiométricos</em>:
- 0.081 mol MgO *
= 0.0407 mol O₂
Finalmente<u> convertimos 0.0407 moles de O₂ en gramos</u>:
- 0.0407 mol O₂ * 32 g/mol = 1.30 g
The speed limit would be 70.2 mi/h
